To all whom it may concern.-

Be it known that I, ABRAHAM L. BUSH, a citizen of the United States, residing at East Oran e, in the county of Essex and State of New jersey, have invented a new and useful Improvement in Railroad Train-Sheds, of which the following is a specification.

This invention relates to the train sheds which cover the tracks of railroad stations or terminals. Sheds of this kind which cover considerable number of tracks are usually constructed in the form of a high vault or arch having covered ventilators at the crown or highest point. Such sheds form an cllicient housing for the passenger platforms,

the tracks, and the trains on the same but have many undesirable features. .l. he first cost of such structures is very large because they require to be made very high in order to 3 place the stecl'work' as tar as practicable above the smoke stacks of the locomotives to reduce the destructive effect of the; steam and gases as much as possible. vaulted and long-span shed does llt-ihpnly rc quire a large amount of material feiits construction but is also very expensive to erect. The cost of maintenance is also very high hect'iusc the shed holds the steam andfgascs' for a considerable length of time and thesteel Work requires to be protected against the destructiveaction of the same by" frequent painting,'and the life of such structures is comparativcly short. 'lhcsc high, vaulted sheds further ca'usc objectionable echoes and noises from thc cxhaust of locomotives and es raping steam and darken the station platforms and cars considerably l ecauscihesky lights are located at a great height above the same.

v The object of this invention is to provide a train shed from which the steam and gases cscape directly into thc outer air, whereby the roof or ceiling of the shed can be arranged at a short distance above the engine smoke stacks, and the many objectionable features of high, vaulted shcds are avoided.

In the accompanying drawings, consisting of three sheets: Figure l is a vertical section of a portion of my improved train shed at right angles to the tracks. Fig. 2 is a fragmentary top plan view of the same. F g. 3 is a fragmentary vertical cross section of the shed, on an enlarged scale. Fig. 4 is a fragmentarylongitudinal view of one of the smoke ducts, on an enlar ed scale, the view being Such a, high partly in section in line i-4, Fig. 6. Fig. 5 1s a similar view in hnc .5 5, Fig. 6. Fig. 6 is a vertical cross section of one of the smoke ducts in line 6-6, Fig. 4. Fig. 7 is a similar cross section in line 7-7, Fig. 4.

Like letters of reference refer to like parts in the several figures.

A represents the tracks and B the passenger platforms which may be arranged in any suitable or convenient way, the arrhngcmcnt represented in Figs. 1 and .2 showing a single track in the outer part of thc shed and two tracks in the next adjoining part.

The upright supports for the roof of the shed may be of any suitable construction, for instance, columns C, or a wall C 'a-rrying columns l) represents the main ra ft ors which arc arranged transversely to the lracksand supportcd at their cnds upon the upright supports in any suitable way and connected lengthwise of the tracks ovcr the columns or supports by longitudinal arched girders l), or other suitable means. The main raflcrs arc {preferably buill-up arched slecl girdcrs and are arranged at a. sullisicnt hcight to clcar the highest locomotive and car in use on the road, as indicated by the dotted lincs F, Fig. 3, ivhich represent the liigllcst locomotive, and the full |incs(i, Fig. 5;, which rep resent the highest car.

The roof or ceiling ll of the shcd, which is supportcd by the rafters and girders, may be of any suitable conslructimi and is providcd with sky lights l and l; in convcnicnt placcs to properly light the platforms and cars.

11 rcprcscnts a duct for the cscape of the stcam, smoke and gascs from thc shed, arrangcd in the roof of lhc shcd lengthwise ovcr each track, so that an cnginc standingwith its smokcstack dircclly undcrncalh this duct will lisclrargetlrc slcam, smoke and gascs directly through the duct, into the throughout the entire length of the shed and is formed bctwecn two longitudinalupright purlins, platcs or walls .\l which arc supported on the main rafters and arraugcd at such a distance apart, transvcrsely to the tracks,- that the duct is of thc propcr width for discharging the steam, smoke and ga'scs without, however, allowing rain and snow cntcring the duct to reach lhc platforms. The purlins M arc cxtcndcd abovc the roof to break the force of driving storms.

IIO-

The longitudinal. duct pnrlins, walls or plates M are preferably-composed of uilt-up steel beams m and a covering m of concrete, as represented in Figs. 44. The main rafters D extend cross the smoke ducts, while the int frmerliitte rafters D, Figs. 2, 3 and 5, which are much lighter or shallower than the main rafters, do not extend across the ducts but terminate at the outer sides of m the same and are secured to plates-m Figs. i and 5, forming part of the built-up steel beams m. The main rafters D are protected. by a coating of concrete Z where they cross the ducts. The duct purlins are preferably :5 extended across the under side of each main rafter L, as shown at m to protect the under side of the rafter and prevent steam, smoke and gases which strike the under side of the rafter within the duct from being deflected 2o laterally he end the duct and into the space outside of t e same and underneath the roof. The under side of the concrete covering oi the rafter within theduct is beveled up:- wardly to deflect the steam, smoke and gases 2 5 end is protected by a facing m of cast iron or other suitable metal.

Each pnrlin or longtiudinal wall of the duct is preferably provided with openings n, Figs. 36, which are arranged beneath the 0 ceiling H in order to permit the escape of any steam or gases which may reach the confined s ace between the outer side of the duct and the ceiling. These openings slope preferably toward the interior of the duct, as shown in Fig. 6, to direct any water whichmay reach these openings into the duct.

When the duct is arranged on the sloping side of the roof, with one pnrlin higher than the other, each main miter is provided in the 0 top of its concrete coveringwith a gutter 0, Figs. 4-7, arranged-lengthwise oi the rafter andv extending through o genings O in the duct purlins for draining '16 water from the high portion of the roof to the low portion.

My improved construction of a train shed provides for the immediate discharge of the steam, smoke and gases into the outer air and so avoids to a large extent the destruc tiv'e effect of the some upon the steel strue-- ture, thereby increasing its life and reducing the cost of maintenance; it also greatly reduces the first cost because the shed is ver low, has short spans, reqiiiros correspond ingly less met-erred and. is readily erected 5 5 without false work or staging; it also reduces the noise arising from escaping steam; mid it locates the sky lights at no great height above the .letiorms and car windows, whereby day lig; it is more copiously admitted to the some.

While the longitni'linal ducts provide for the immediate and free escape of the steam, smoke and gases from the shed, they odmit snow and rain, but as they are comparan': lively narrow the snow and rain cannot the pnssenger platforms but fell on the trucks or the car roofs, where snow and rsir are-not objectionable.
